MELANGEUR INTERNE A ROTORS PERFECTIONNES INTERNAL MIXER WITH IMPROVED ROTORS
La présente invention se rapporte aux mélangeurs internes. The present invention relates to internal mixers.
Plus particulièrement elle concerne la définition du profil More particularly it concerns the definition of the profile
des ailes dont sont pourvus ces rotors. wings with which these rotors are provided.
Les mélangeurs internes sont des malaxeurs à marche discontinue convenant pour la préparation du caoutchouc et d'autres matières plastiques. Ils comportent une cuve fermée à une ou deux chambres cylindriques communicant entre elles, chaque chambre comportant un rotor.Chaque rotor comporte une ou plusieurs ailes. On caractérise le rotor par son profil (section par un plan perpendiculaire à l'axe de rotation donnant notamment le profil des ailes) et par son diagramme qui est un développement à plat sur un plan parallèle à l'axe de rotation, donnant le positionnement des ailes à la surface du rotor, notamment la position, l'orientation par rapport aux bords, et l'étendue de la zone d'écart minimum entre la paroi de la chambre et la surface The internal mixers are batch mixers suitable for the preparation of rubber and other plastics. They have a closed vessel with one or two cylindrical chambers communicating with each other, each chamber comprising a rotor. Each rotor comprises one or more wings. The rotor is characterized by its profile (section by a plane perpendicular to the axis of rotation giving in particular the profile of the wings) and by its diagram which is a flat development on a plane parallel to the axis of rotation, giving the positioning wings on the surface of the rotor, in particular the position, the orientation with respect to the edges, and the extent of the zone of minimum distance between the wall of the chamber and the surface
du rotor (zone appelée dans la suite "passage au fin"). of the rotor (hereinafter called "passage to the end").
Le choix et la combinaison du nombre de chambres et du type de rotor dépendent de la composition des mélanges de caoutchouc ou matières plastiques à réaliser. Les mélangeurs internes les plus répandus pour la préparation du caoutchouc non vulcanisé comportent deux chambres et deux rotors non engrenants, tournant en sens opposés à des vitesses différentes. On en voit un exemple dans le brevet The choice and combination of the number of chambers and the type of rotor depends on the composition of the rubber or plastic mixtures to be produced. The most common internal mixers for the preparation of unvulcanized rubber have two chambers and two non-meshed rotors, rotating in opposite directions at different speeds. We see an example in the patent
US 4 456 381.US 4,456,381.
Le but recherché dans les mélangeurs internes est de forcer les constituants du mélange à passer d'une chambre à l'autre et, à l'intérieur d'une chambre, d'un côté à l'autre, dans le sens axial de celle-ci, et aussi à forcer le mélange à The aim sought in internal mixers is to force the constituents of the mixture to pass from one chamber to another and, inside a chamber, from one side to the other, in the axial direction of that and also to force the mixture to
passer entre les pales des rotors et les parois 'de la cuve. pass between the rotor blades and the walls of the tank.
Ceci permet de réaliser une macro dispersion des constituants et une micro dispersion des additifs. La macro dispersion est plutôt le fait du transfert de masse de -2- matière entre les chambres de la cuve et des transferts axiaux, c'est-à-dire le long des ailes du rotor dans chacune des chambres, alors que la micro dispersion est plutôt conditionnée par le passage entre l'aile et la paroi de la chambre. Les rotors de mélangeurs internes ont l'inconvénient de présenter, dans la partie de passage au fin, une zone de travail intense de longueur courte, qui sollicite les matériaux de manière brutale et irrégulière, pouvant provoquer des glissements importants ainsi que pour certains élastomères des décohésions accompagnées d'un mauvais état de mélangeage. La figure 1 est une vue d'un profil d'aile de rotor 1 selon lart antérieur. En particulier, on remarque la présence d'arêtes vives 20 qui délimitent de part et d'autre la zone de passage au fin 21. On définit le côté avant du passage au fin 21 en quittant celui-ci dans le sens de rotation du rotor 1 (flèche 11) qui correspond donc au convergent matérialisé par la surface de l'aile en coopération avec la paroi de la chambre 2. A l'inverse, le This allows a macro dispersion of the constituents and a micro dispersion of the additives. Macro dispersion is rather the result of the mass transfer of -2- material between the chambers of the tank and axial transfers, that is to say along the wings of the rotor in each of the chambers, while micro dispersion is rather conditioned by the passage between the wing and the wall of the chamber. The rotors of internal mixers have the disadvantage of having, in the passage portion at the end, an intense working area of short length, which stresses the materials in a brutal and irregular manner, which can cause significant slippage as well as for certain elastomers of the decohesions accompanied by a poor state of mixing. Figure 1 is a view of a rotor wing profile 1 according to the prior art. In particular, we note the presence of sharp edges 20 which delimit on both sides the passage zone at the end 21. The front side of the passage at the end 21 is defined by leaving it in the direction of rotation of the rotor. 1 (arrow 11) which therefore corresponds to the convergent materialized by the surface of the wing in cooperation with the wall of the chamber 2. Conversely, the
côté arrière est situé du côté opposé par rapport au sens de- rear side is located on the opposite side from the direction of-
rotation. On remarque également que, en arrière du passage au fin 21, on a un accroissement brutal et important de rotation. We also note that, behind the passage at the end 21, there is a sudden and significant increase in
l'écart entre l'aile 10 et la paroi de la chambre 2. the distance between the wing 10 and the wall of the chamber 2.
D'autre part les mélangeurs internes connus ne peuvent assurer une bonne maitrise des échanges thermiques lors du On the other hand, the known internal mixers cannot ensure good control of the heat exchanges during the
cycle de mélangeage.mixing cycle.
Le but de la présente invention est d'améliorer la micro dispersion obtenue par l'action d'un mélangeur interne, en proposant une nouvelle conception du profil d'une aile de mélangeur interne. Un autre objectif de l'invention consiste à améliorer la capacité d'une aile ainsi optimisée à évacuer les calories dégagées par l'opération de mélangeage. Selon l'invention, le mélangeur interne comportant une cuve de mélangeage constituée par au moins une chambre cylindrique dans laquelle tourne un rotor, ledit rotor comportant au moins deux ailes inclinées en sens opposés, le -3- profil de l'aile définissant avec la paroi de la chambre un convergent puis un divergent, séparés par un passage au fin, est caractérisé en ce que, de part et d'autre du passage au fin, la courbure du profil est sensiblement constante, et en ce que, écarté du passage au fin dans le sens opposé au sens de rotation de l'aile, le profil comporte un décrochement, suivi toujours-dans le sens opposé au sens de rotation, d'un second divergent plus accentué que le divergent compris entre le passage au fin et le décrochement. Un rotor de mélangeur interne perfectionné suivant l'invention est remarquable par le fait qu'il n'existe pas d'arêtes vives dans la partie de passage au fin o se produit la sollicitation la plus intense. En effet la partie- convergente a un profil convexe. Ce profil est sensiblement conservé dans le passage au fin et après celui-ci. Donc le début du divergent, juste en arrière du passage au fin, est très progressif. Il y a un relâchement lent et progressif de la sollicitation au delà du passage au fin, contrairement à la technique antérieure o le passage au fin marque également la rupture de la continuité du profil. Les' profils des ailes des rotors connus présentent donc un convergent, parfois progressif, un passage au fin, puis un divergent important. Le profil proposé par la présente invention présente successivement un convergent progressif, un passage au fin, un divergent progressif, puis une zone de rupture de la continuité du profil, appelée The object of the present invention is to improve the micro dispersion obtained by the action of an internal mixer, by proposing a new design of the profile of an internal mixer wing. Another objective of the invention consists in improving the capacity of a wing thus optimized to evacuate the calories released by the mixing operation. According to the invention, the internal mixer comprising a mixing tank constituted by at least one cylindrical chamber in which a rotor rotates, said rotor comprising at least two wings inclined in opposite directions, the profile of the wing defining with the wall of the chamber a convergent then a divergent, separated by a passage at the end, is characterized in that, on either side of the passage at the end, the curvature of the profile is substantially constant, and in that, spaced from the passage at the end in the direction opposite to the direction of rotation of the wing, the profile comprises an offset, always followed in the direction opposite to the direction of rotation, of a second divergence more accentuated than the divergence comprised between the passage at the end and the dropout. An improved internal mixer rotor according to the invention is remarkable in that there are no sharp edges in the passage part at the end where the most intense stress occurs. Indeed, the converging part has a convex profile. This profile is substantially preserved in the passage at the end and after it. So the beginning of the divergent, just behind the passage at the end, is very progressive. There is a slow and progressive relaxation of the stress beyond the passage at the end, unlike the prior art where the passage at the end also marks the rupture of the continuity of the profile. The 'profiles of the wings of known rotors therefore have a convergent, sometimes progressive, a passage at the end, then a significant divergence. The profile proposed by the present invention successively presents a progressive convergent, a passage at the end, a progressive divergent, then a zone of rupture of the continuity of the profile, called
décrochement, suivie d'un divergent accentué. drop, followed by an accentuated divergence.

Pour rappel, la figure 1 illustre l'art antérieur. As a reminder, Figure 1 illustrates the prior art.
A la figure 2, on aperçoit un rotor 1, une aile 10, et la paroi de la chambre 2 dans laquelle le rotor se trouve In FIG. 2, we can see a rotor 1, a wing 10, and the wall of the chamber 2 in which the rotor is located.

-4- disposé. L'aile 10 définit, avec la paroi de la chambre 2, un convergent 23 puis un passage au fin 21. Il y a une distance très nette entre le passage au fin 21 et la zone dite de décrochement 22, séparant un premier divergent 24 -4- arranged. The wing 10 defines, with the wall of the chamber 2, a convergent 23 then a passage at the end 21. There is a very clear distance between the passage at the end 21 and the so-called recess zone 22, separating a first diverging point 24
progressif, d'un second divergent 25 très accentué. progressive, from a very divergent second divergent 25.
Le convergent Z3 du profil est défini dans un plan perpendiculaire à l'axe du rotor par un centre C et un rayon de courbure R. Le rayon de courbure est constant le long de l'aile. Le centre de courbure C est tel que sa distance à l'axe du rotor O est comprise entre des valeurs 0,1 Ro et 0,6 Ro o Ro est le rayon de la cuve. Le rayon de courbure R est lui compris entre les valeurs 0,4 Ro et 0,7 Ro. Le passage au fin 21 est défini dans un plan perpendiculaire à l'axe par le point A de distance maximale à l'axe du rotor, The convergent Z3 of the profile is defined in a plane perpendicular to the axis of the rotor by a center C and a radius of curvature R. The radius of curvature is constant along the wing. The center of curvature C is such that its distance from the axis of the rotor O is between values 0.1 Ro and 0.6 Ro o Ro is the radius of the tank. The radius of curvature R is between the values 0.4 Ro and 0.7 Ro. The passage at the end 21 is defined in a plane perpendicular to the axis by the point A of maximum distance from the axis of the rotor,
autrement dit d'écart minimal avec la paroi de la chambre 2. in other words a minimum distance from the wall of chamber 2.
Le divergent 24 juste après le passage au fin 21 comporte un profil conçu de la même façon (rayon de courbure choisi dans le même intervalle). Le point B qui est la trace d'une arête vive, matérialise dans cet exemple le décrochement 22 et est situé à une distance huit fois supérieure au jeu entre le point A et la paroi de la chambre. Ces caractéristiques géométriques ont été déterminées de façon expérimentale et permettent de réaliser, en adoptant le diagramme représenté à la figure 3, d'excellentes The divergent 24 just after the passage at the end 21 has a profile designed in the same way (radius of curvature chosen in the same interval). Point B which is the trace of a sharp edge, materializes in this example the recess 22 and is located at a distance eight times greater than the clearance between point A and the wall of the chamber. These geometric characteristics have been determined experimentally and make it possible to achieve, by adopting the diagram shown in Figure 3, excellent
performances de macro dispersion et de micro dispersion. macro dispersion and micro dispersion performances.
Sur ce diagramme, on voit que l'on dispose deux ailes 10 s'étendant dans la direction axiale sur une longueur comprise entre 0.6 Lo et 0.8 Lo, o Lo est la longueur du rotor 1. Les ailes 10 sont inclinées d'un angle compris In this diagram, it can be seen that there are two wings 10 extending in the axial direction over a length of between 0.6 Lo and 0.8 Lo, where Lo is the length of the rotor 1. The wings 10 are inclined at an angle including
entre 15' et 30'.between 15 'and 30'.
Un tel profil permet une sollicitation progressive du matériau entre la paroi de la chambre et le rotor à chaque passage de la matière. Il n'existe plus de sollicitations brutales. Il permet aussi un accompagnement de la matière après le passage au fin qui permet une relaxation du matériau. Un tel profil permet de plus une bonne microdispersion des charges renforçantes. Grâce à cette solution, on évite les décohésions du matériau amenées par des glissements importants à la paroi, observées dans l'art - 5 - antérieur, ce qui permet d'obtenir un meilleur état final de mélangeage. Enfin un rotor 1 de mélangeur interne perfectionné suivant l'invention comporte une chambre 12 de refroidissement localisée de préférence et principalement sous le convergent 23 dans la zone o se produisent les dégagements de chaleur les plus intenses (figure 4 et 5). La totalité du débit de réfrigérant est utilisée pour obtenir un échange thermique optimal, les chambres de refroidissement étant en série, comme cela apparaîlt à la figure 5. Le rotor 1 suivant l'invention offre une résistance mécanique suffisante pour l'installation de telles chambres dans les zones de travail Such a profile allows progressive loading of the material between the wall of the chamber and the rotor at each passage of the material. There are no longer any brutal requests. It also allows support for the material after the passage at the end which allows relaxation of the material. Such a profile also allows good microdispersion of reinforcing fillers. Thanks to this solution, the decohesions of the material brought about by significant slippages to the wall, observed in the prior art, are avoided, which makes it possible to obtain a better final state of mixing. Finally, a rotor 1 of an improved internal mixer according to the invention comprises a cooling chamber 12 preferably located and mainly under the convergent 23 in the zone where the most intense heat releases occur (FIGS. 4 and 5). The entire refrigerant flow is used to obtain optimal heat exchange, the cooling chambers being in series, as shown in FIG. 5. The rotor 1 according to the invention offers sufficient mechanical strength for the installation of such chambers in work areas

Il est bien clair que différentes modifications peuvent être apportées aux ailes de mélangeurs internes sans sortir du cadre de la présente invention chaque fois que l'on en reproduira les caractéristiques essentielles portant sur le It is quite clear that various modifications can be made to the wings of internal mixers without departing from the scope of the present invention each time the essential characteristics relating to it are reproduced.
